Air separation plants Linde supplied over 3,000 air separation plants for the production of oxygen, nitrogen, argon and rare gases (krypton and xenon) world-wide. The Linde portfolio ranges from modular designed plant with 50 Nm3/h oxygen capacity to tailor made single unit tonnage plants of 110,000 Nm3/h oxygen capacity. The largest parallel unit plant under construction will have a capacity of 860,000 Nm3/h oxygen.

Major references in Southern Africa Linde supplied several air separation plants to clients like – Sasol – PetroSA (2 x 63,000 Nm³/h oxygen for GTL) – Afrox (since 2006 a member of The Linde Group)

Coil-wound heat exchangers Cryogenic standard tanks Aluminium plate-fin heat exchangers Coil-wound heat exchangers (CWHE) have been Linde fabricates a wide range of standard The fabrication facility of Linde in Germany is used in the industry since the early days, when vacuum-insulated cryogenic storage tanks well known as a highly competent supplier for Carl von Linde liquefied air on an industrial scale for storage of liquefied gases. aluminium plate-fin heat exchangers, a quite for the first time in May 1895. The current range of standard tanks covers ope- sophisticated type of cryogenic equipment. Until today, more than 1,000 coil-wound heat rating temperatures from -196 ºC up to +20 ºC, These aluminium plate-fin heat exchangers have exchangers have been manufactured in Linde´s pressures up to 18, 22 and 36 bar and liquid been manufactured by vacuum brazing technol- fabrication facilities in Germany. volumes from 3,000 litres up to 80,000 litres. ogy since 1981. Since that time more than 6,000 Coil-wound heat exchangers are compact and heat exchanger cores have been produced. reliable with a broad temperature and pressure The Linde cryogenic standard tanks are typically Linde plate-fin heat exchangers can be used for range and suitable for single phases as well as used for the storage of: a wide range of applications, especially for low two phase streams.
